JOHN E. LEVAN, OF ELKHART, INDIANA, ASSTGNOR TO THE 0. M. ZEDWARDS INQ, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK AUTOMATIC ADJUSTABLE WEATHER-STRIP FOR WINDOW SASHES Application filed April 4, 1930. Serial No. 441,625.

object, aparticularly simple and eflicient means for carrying a weather strip which coacts with one of the wlndow stops and PTQSS.

ing the weather strip against said stop, which means also may if desired, be so mounted as to permit a widthwise adjustment with n limits, so that the sash is readily fitted n window guides or post structures mounted in the window openings, which openings although intended to be exactly the same, vary somewhat in width.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

F igurel is a fragmentary elevation of a window construction embodying my invention. 1

Figure 2 is a transverse sectional view on line 2-2, Figure 1. V

Figure 3 is a transverse sectional view of the weather strip supporting member.

Figure 4 is an edge view of the sash showing thetransverse slots therein.

Figure 5 is a fragmentary elevation of the weather strip supporting member showing the transverse slots therein.

l designates the window frame or post structure, which may be of any suitable form, size and construction, it being here shown as formed up of sheet metal, thisframe 1 being fixed to the car body and confining the window opening in any suitable manner. The widthwise spacing of the post structures vary within limits, as will be understood by those skilled in the art.

The frame or post structure is provided with inner and outer window stops 2, 3 which form a sash guide or channel. These stops are secured to the post structure in any well known manner. One of the stops, preferably the outer stop, is formed with an internal offset-channel portion 4 located beyond the face of the sash 5. This stop 3 is also formed with an outer rolled or beaded edge portion 6; I

he'sash 5 is here shown as formed 111p1 of sheet metal, so that it is hollow and lig which is received, a channel member8 receiving the margin of the glazing9; L

This invention relatesto a=weatherstr1p and means for supporting it at the edgeof the sash, and between the window stops 2, 3,'in

' such a manner that itengages one of the stops and preferably, the stop formed with a recess 1, and extends into such recess, and means for pressing the Weatherstrip against the 2, 3, the channel opening towardone of the 1;.1 It is formed witha suitable reentrant groove 7in*- stops, as theouter stop 3; This channel is- I provided in an adjustable member 12 having a body 1 shaped to snugly embrace the sash f and be capable of a widthwise'adjustmentto conform, within limits, to the variations in spacing of the post structures. It will be understood that, there is a post structurefat each side of the sash, and also a Weatherstrip and its supporting means at each edge of the,

1 sash, and thatthe Weatherstrip and its 'supporting orholding means extends the full length of each edge of the' sa'sh, The member 12 is preferably "formed up of sheet metal to provide the channel which receives the sash, and the channel 11 for'the weather strip 10, and said member 12 is also provided with a lip 13 on its outer side over hanging the edge of the stop'3 to deflect air currents away from the crevice or joint between the member 12 and th'estop 3.

The adjustable member 12 and the channel 11 per se form no part of this invention, these of Roy T. Axe, Ser'. N 0. 431,57 9, filed Februbeing the subject matter of the applications ary 26, 1930 and Ser. No. 375,133, filed July" 1,1929. 7 V The weather strip is here shown, as mounted in a holder 14 U shaped in cross sec ,tion, slidably mounted in the channel 11, and

the holder is interlocked with the" channel and also withthe'sash, to permit transverse V movement of the weather strip, but to prevent endwise movement relatively to the sash during the raising and lowering of the sash.'

The conenctions between the weather strip and its holder 14c, and the sash, are here shown 5. as pins15 extending transversely through the holder '14 and the inter-posed weather str p, and projecting beyond the sides of the holder into transverse slots 16 formed in opposite.

sidewalls vof thechannelll, and into transverse slots 17 formed in the edge wall of the sash.

The weather strip and itsv holder is pressed outwardly by springs 18 interposed between the bottomof the channel 11. andlthebottom' of the holder 14. The springs illustrated, are

coiled compression: springs; Any I suitable V spring-oriresilientirneans' maybe used. The outer margin of the Weatherstrip, as before stated,projectsinto the recess 4 and engages 2.0 theawalls'thereof, andis pressed in weather tight engagement therewith by the springs 18.

' Thesash is providedtviththe usual sash holders-,rinot shown,'.or so-called sash locks,

"' i This :lIIVBIItIOII lS particularly advantage 1 ous in that the weather strip 10 is always pressed toward the outer'stoplinto snug engagement therewith, so; that the sash is s weather tight. regardless-bf whether, the lip.
